This arrangement of shingles gives a secure and permanent fastening. and with but a single nail employed for each shingle.

In the first vertical row of shingles extra nails are employed to hold down the lower left-hand corners, but in the body of the roof the same number of nails are employed as there are shingles.

.As shown in Figure 1, the shingles are aligned, in rows running transversely and longitudinally of the roof. This gives a uniform square thatch which is pleasing in appearance.

I claim:

1. In a roof comprising a plurality of shingles having a pair of locking corners and a pair of non-locking corners, a shingle laid in one course, a second shingle laid in an underlying course and positioned with one of its non-locking corners overlapping a locking corner of said first shingle, a nail through said lapping corners, and a third shingle laid in a course with the first shingle and positioned with a locking corner overlapping said nailed corners and interlocked with the locking corner of the first shingle.

2. In a roof comprising a plurality of shingles having a pair of locking corners and a pair of non-locking corners, a shingle laid in one course, a second shingle laid in an underlying course and positioned with one of its non-locking comers overlapping a locking corner of said first shingle, another shingle in the underlying course and positioned with one of its non-locking corners underlapping said lapped corners, a nail through all three of said lapp nz corners, and a-fourth shingle laid in a course with the first shingle and positioned with a locking corner overlapping said nailed corners and interlocked with the locking corner of the first shingle.

3. In a roof comprising a plurality of rectangular shingles having a locking tab at one lower corner, a receiving slit at the other lower corner, and having plain right angular upper corners, a shingle laid in one course, a second shingle laid in an underlying course and positioned with one of its plain comers overlapping the slitted corner of said first shingle and with its upper edge adjacent the upper end of the slit, another shingle in the underlying course and positioned with one of its plain corners underlapping said lapped corners and also having its upper edge adjacent said slit, a nail through all three of said lapping corners. and a fourth shingle laid in a course with the first shingle and positioned with its tabbed corner overlapping said nailed corners and with its tab engaging said slit of the first shingle.
